Bearing packer?
May I ask a dumb question? What kind of bearing packer are people using? I see some of them have Zerk fittings and some don't. Which is better?

In my neck of the woods this is popular. I think if you shop this item it can had for less money else where, maybe.

On solvents, I had always been taught to use Stoddard Solvent for aviation work, and have done that for years too - but nowadays, its hard to find by that name. I did some research, and it turns out that Stoddard is another name for Mineral Spirits, so that is what I have been using lately. Much less likely to go "boom" than gasoline or Avgas (which I have also used in a pinch, but prefer not to take the risk if I don't have to. |

Stoddard solvent is my preference if cleaning out all the way. Have been known to use mineral spirits, diesel fuel, and Jet A but NEVER gasoline or 100LL. Did not know mineral spirits and Stoddard solvent was the same thing. Around my airport, people talk about using Varsol. Sounds like we all use the same thing but has different names. |
The 104 flash point safety clean was my favorite in a solvent tank, then emissions regulations started taking over and then 140 flash point, did not clean as well, then the orange juice solvent, then the heated water base with soap and live bugs that eat grease, take the parts out and then they would rust. Then they took our solvent tank away! so now we use cans and cans of brake clean........what fumes? bet you can't guess what state this is.........getting rid of hazard material is expensive. By the time you buy many cans of cleaner, you could probably buy new bearings and pack them.......

Diesel
I've started using diesel for most parts cleaning. It's much cheaper than mineral spirits; just take an empty gallon oil jug to the service station. If left uncovered when you're not around for a bit, most of the smell goes away.

Stoddard solvent or mineral spirits depending what I have and then rinse with brake cleaner. Always thought having the solvent residue left on the bearing could break down the new grease. Brake clean leaves very little residue.
A lot easier to inspect bearing for pitting if you clean them before packing with fresh grease. |
Sounds like mineral spirits and brake cleaner is the ticket. I have so much brake dust from dragging brakes I don't want to just push more grease in. Now working on what is dragging the brakes.
